Abstract: The adnexal masses during pregnancy include physiological cysts， inflammatory masses， benign neoplasms and malignant neoplasms， and its incidence has been increasing in recent years. Physiological cysts usually spontaneously resolve in the middle or late stage of pregnancy or after delivery. Benign ovarian neoplasms without complications or obstruction of the birth canal can be closely observed during pregnancy，while malignant ovarian neoplasms which endanger the safety of both mothers and fetuses require active intervention. Therefore， it is of great significance to make diagnosis and differential diagnosis of ovarian malignant neoplasms in pregnancy. During the diagnostic process， the results of imaging tests and tumor markers need to take pregnancy into consideration. This article mainly describes the diagnostic methods and characteristics of adnexal mass during pregnancy.

摘要： 妊娠期附件包块包括生理性包块、炎性包块、良性肿瘤、恶性肿瘤等，近年来发生率有上升趋势。妊娠期卵巢生理性包块多在妊娠中、晚期或产后自行消失；卵巢良性肿瘤若无并发症出现，未阻塞产道，妊娠期可密切观察；而妊娠期卵巢恶性肿瘤危及母胎安全，需积极干预处理。因此，孕期对于卵巢恶性肿瘤的诊断和鉴别诊断具有重要的意义。在诊断过程中，影像学检查及肿瘤标志物的结果需考虑妊娠本身的影响。文章主要阐述妊娠期附件包块的诊断方法及特点。
